V BROOM.

Application filed nugus't 11, 1919. Serial No. 316,610.

To all whom it may concern Be i't'knownthat I, EDWARD KRANTZ, acitizen of the United States, resi'ding at Chicago, in the county of Cook, State of Illinois, have invented certain new :and useful Improvements in Brooms, of which the followingis a specification.

This invention rel-ates to a novel form of broom wherein provision is made tor the renewal of the head thereof;

The present invention aims to provide a construction of renewable broom primarily designed for deep penetration of the handle into the straw of the 'broo-mdiead, thus establishing such relation of the head and handle as to resist effectually the strain imposed thereon when in use, and. thereby to obtain a. rigid mounting of the handle in the head which is of great strength and. in which liability to brealrage is reduced to a minimum.

The invention also has-in View the production of abroom of the character referred to embodying simple and efficient means for locking, the head and handle in assembled relation, the construction and arrangement of the parts being such as to enable their manufacture :at low cost, thereby permitting the broom to be madeand sold at a figure very little in excess of the usual form of non-renewable broom commonly in use, and also providing-a broom of greater utility than the ordinary Et'orm.

@ther objects and advantages will appear as the nature of the iniparovements'is better understood, the invention consisting substantially in the novel construction, combination and arrangement of the parts hereinafter iiiill'y described, illustrated in the accompanying drawings, and finally pointed out in the appended claims. the invention is. herein set forth in one of its forms, the same is to be considered only as an illustrative embodiment thereof, and such disclosure is, therefoienot "to be taken in a "limiting 'or restrictive sense.

.In the drawings: I

Figs. 5 and h are sectional plan views on the lines 55 and"66, Fig. '2.

Referring now in detail to the drawings, the numeral '10 designates the broom head and 11 the stickor handle thereof. The head 10 is formed of broom straw in the customary way, the same being provided with rows of thread 12 holding the straw together and preserving the configuration of the head.

Arranged at the top of the broom head 10 is a clasp 13 which is preferablyformed of sheet metal. "This clasp includes apair of oppositely disposed wings or clasp members 14 which extend symmetrically in opposite directions transversely of the top of the broom head and bend downwardly a short distance to enibrace the upper portions of the sides thereof. These wings are either integrally or otherwise associated with an elongated ferrule 15 which is also preferably formed of sheet metal, and are carried by the same on opposite sides thereof.- The ferrule is arranged with its axis coincident with the .axis of symmetry of both wings 14', and is of such length as'to penetrate the straw of the head 10 and become firmly seated therein. The interior of the ferrule 15 is screw threaded, as at 1'6, for a purpose to bepresently recited.

At each end of the above-describec'l wings or claspmembers '14 is a laterally extending tongue '17 which curves inwardly about the adjacent end of the broom head 'toward the corresponding tongue on the opposite .member. These opposed tongues, which are disposed .in pairs at each of the ends of the broom head, are designed .to lie with their adjacent edge portions in co-planar relation, asclearly illustrated in Fig. 6. By referring to that figure it is to be noted that the tongues 17 of one of the wings 14 are provided .at their extremities with inwardly ofl'se'tflanges 18, said flanges being ra bbeted', as at .19, to provide guiding shoulders against which the sides of the tongues of the opposite member 14 may rest. By this provision the contiguous tongues lie in aligned relation, and a'fiordan even surface at the ends of the clasp. Passing through the broom straw, and connecting the opposite wings 14, is a plurality of rivets 20 by means .of'which the clasp 13 isfheld on the broom head 10. 7

Eachof the wings '14 is also provided with a series of corrugations 21, said-corrugations IOU ' ment with the ferrule 15.

affording means for interlocking the wings with the broom straw, and thus adding further means for effecting engagement of the clasp 13 with the head 10. These corrugations 21 also strengthen the wings 14L For the purpose of holding the head 10 in proper relation to the handle 11 a socket member 22 is employed. The configuration of this socket member 22 is of such character that the clasp'ftS will snugly l t therein, and at the central portion of the socket 20 an upstanding ferrule 23 is formed which is designed to receive the lower end of the handle 11. The latter is pointed, as at 24, to readily penetrate the straw, and that portion of the handle immediately adjacent the pointed end 24 is slightly reduced in diameter so as to fit with nicety the ferrule 23, and likewise the ferrule 15. This reduced portion is screw threaded, as at 25, to engage the screw threads 16 of the ferrule 15, and at the upper extremity of said re duced portion of the handle a shoulder 26 is formed designed to abut against the ferrule 23.

It is quite desirable that the screw-thread ed portion 25 of the handle 11 be substantially the same diameter as the remaining por tion of the handle and therefore be reduced in diameter only as much as is necessary in the formation of the shoulder 26, as it is the portion 25 of the handle which receives the most severe strains when the broom is in use, and a decided reduction in diameter at such point would make the advantageous employment of the economical one-piece wooden handle impracticable. Accordingly, as shown in the drawing, the portion 25 of the handle is substantially the same diameter as the remaining portion of the same, and the ferrule 15 which encompasses the portion 25 is likewise substantially the same large diameter.

In assembling the herein described broom, it will be understood that the clasp 13 forms a permanent part of the head 10. The head 10 and the clasp 13, therefore, constitute a unit complete in itself. To engage the hanvdle with the broom head 10 the socket 22 is applied to the clasp 13, and in this application the ferrule 23 is brought into aline- The pointed end 24: of the handle 11 is now passed through the ferrule 23 and the screw threads 25 caused to engage the screw threads 16 of the ferrule 15. By continued rotation of the handle 11 the pointed end of the latter is advanced into the broom straw until the shoulder 26 abuts against the ferrule 23. When this condition arises the socket 22 and the clasp 13 are tightly engaged, and the handle 11 rigidly connected to the broom head 10, and in such condition the ferrules 15 and 23 constitute prolongations of each other, thereby affording a substantially continuous reinforce for the handle 11 at its deeply imbedded inner end and outwardly thereof to a point beyond the socket 22.

By reason of the deep penetration of the pointed end of the handle 11 into the straw of the head 10 and the fact that the ferrule 15 is likewise deeply embedded in the straw, a strong connection of the handle with the broom head is afforded, and this is sufiicient to resist, wihout breaking, the greatest strain imposed upon the broom in its ordinary use. Furthermore, the handle andthe broom head are effectually locked together, and the parts held in rigid relation with respect to each other.

The broom head 10 and the clasp 13 forming an independent unit complete in itself, as above set forth, enables stocks of the same to be carried, and when the head associated with the handle as the broom is originally purchased has become worn to such an ex tent as to be of no further use the same may be detached from the handle and a new head substituted therefor.

While the invention is illustrated and de scribed primarily with respect to brooms generally it will be understood that the same may be incorporated in brushes and similar structures. Where, therefore, reference herein has been made to brooms, the extended use mentioned is contemplated.

I claim I 1. In a broom, the combination with a head comprised of a body of broom, straw having a clasp fixedly connected to the upper end of said body and embracing and securing the straw, said clasp having. an elongated ferrule penetrating the embraced end of the straw and embedded therein, a socket into which said head is fitted, said socket having an upstanding ferrule in alinement with the ferrule of the head to afford a substantially continuous reinforcement for a handle at the point of its engagement with the head, and a handle ar ranged in said ferrules and provided'with a shoulder in abutment with the ferrule of the socket, said handle having .means 00- operating with the ferrule of said head to establish tight engagement between the socket and the clasp.

2. In a broom, a head composed of a body of broom straw, a clasp fixedly connected to the upper end of said body and embracing and securing the straw, a ferrule penetrating the embraced end of the straw and embedded therein, a socket into which said head is fitted, said socket having an .up-. standing ferrule in alinement with: the ferrule of the head to afford a substantially continuous reinforcement for a handle at thepoint of its engagementwith the head, and a handle removably arranged within said ferrules, said handle having means cooperating with the-ferrule of thesocket to.

limit movement of the socket in one direction longitudinally of the handle, and having meanscooperzvting with the ferrule of the head to establish tight engagement between the socket and the clasp.

3. In a broom, a head composed of a body of broom straw, a clasp of sheet metal fixedly connected to the upper portion of said body and embracing and securing the straw, a threaded ferrule of sheet metal penetrating the embraced end of the straw and embedded therein, a socket into which said head is removably fitted, and a handle having a threaded end portion of integral formation extending through the socket into 15 for holding the socket against movement 20 up the handle. 1
